[shukla41196]

I Want to apply data reduction techniques like integration, differentiation windows and filters which is required,Then want to plot spectrogram, The data is large in numbers(about 2million). Please explain the sequence of functions I should apply or give some example.

Hi shukla,

I Want to apply data reduction techniques like integration, differentiation windows and filters which is required,Then want to plot spectrogram,

This sounds like a good plan!

What have you tried so far?

The data is large in numbers(about 2million).

2 million samples is not so much…

Please explain the sequence of functions I should apply

First "data reduction" (whatever this means), filters and then plotting to a graph…

Again: What have you tried and where are you stuck?

I have tried bandpass filter and STFT spectrogram VI and windowing function. But I don't know right order of their application.

Hi shukla,

But I don't know right order of their application. 

The point is: what is YOUR application (aka: requirement)?

First you need to define your requirements, then you should start coding…
